Exploring risk factors and antimicrobial susceptibility patterns associated with bacteriuria among Syrian refugees in makeshift camps.

Background: The health and well-being of refugees are critically compromised by harsh living conditions, which foster the emergence of infectious diseases and the misuse of antimicrobial agents. This multicentre cross-sectional community-based study investigated the prevalence of urine carriage of bacteria and the associated antimicrobial resistance patterns among Syrian refugees living in makeshift camps in Lebanon, an East Mediterranean country.

Methods: We used multivariable logistic regression models to identify the risk factors associated with bacteriuria in this vulnerable population.

Individualistic reward-seeking strategies that predict response to nicotine emerge among isogenic male mice living in a micro-society.

Individual animals differ in their traits and preferences, which shape their social interactions, survival, and susceptibility to disease, including addiction. Nicotine use is highly heterogenous and has been linked to the expression of personality traits. Although these relationships are well documented, we have limited understanding of the neurophysiological mechanisms that give rise to distinct behavioral profiles and their connection to nicotine susceptibility.

Transient nicotine exposure in early adolescent male mice freezes their dopamine circuits in an immature state.

How nicotine acts on developing neurocircuitry in adolescence to promote later addiction vulnerability remains largely unknown, but may hold the key for informing more effective intervention efforts. We found transient nicotine exposure in early adolescent (PND 21-28) male mice was sufficient to produce a marked vulnerability to nicotine in adulthood (PND 60 + ), associated with disrupted functional connectivity in dopaminergic circuits. These mice showed persistent adolescent-like behavioral and physiological responses to nicotine, suggesting that nicotine exposure in adolescence prolongs an immature, imbalanced state in the function of these circuits.

Recent advances in three-dimensional ultrasound virtual cystoscopy in modeling and local staging for urothelial carcinoma with histopathological correlation: a cohort prospective study.

Background: Bladder urothelial carcinoma is an alarming urologic malignancy. Complex factors like modelling and local staging can affect treatment strategy. However, local staging, particularly the muscle invasion status, significantly influences decisions regarding treatment strategies.
